Superimposed single-photon emission computed tomography and X-ray computed tomography of the heart: Methodical aspects

open access: yesВестник рентгенологии и радиологии, 2016
Global radiology and nuclear medicine have recently shown a clear trend towards hybrid (combined, superimposed) studies. Unfortunately, the Russian literature virtually lacks both methodological and research works on this topic.

Requirements and Evaluation of Commercial Digital Light Processing 3D Printers for Upscaled Production of Microstructured Tissue Culture Devices

open access: yesAdvanced Engineering Materials, EarlyView.
Commercial light‐based 3D printers increasingly find use for industry‐scale production of microstructured tissue culture devices. How can commercial printer performance be assessed for a given application? This work introduces simplified quantitative metrics based on microstructural fidelity analysis, addressing key manufacturing challenges in scaling ...

Deformation Behavior of Optical Ceramic Nanomultilayers: The Role of Aperiodicity

open access: yesAdvanced Engineering Materials, EarlyView.
Ceramic nanomultilayers demonstrate optical and mechanical behavior tunability through aperiodicity. Within the studied systems, optically optimized coatings exhibit an average ultraviolet, visible, and near‐infrared spectral transmittance above 90%.

3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

open access: yesAdvanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Multimode Adaptive Thermoregulation Enabled by Shape Morphing and Radiative Cooling Porous Polyurethane

open access: yesAdvanced Engineering Materials, EarlyView.
A shape‐morphing, porous polyurethane film combines passive radiative cooling with folding to deliver multilevel heating‐and‐cooling control. High solar reflectance and midinfrared emissivity keep surfaces up to 3.5 °C cooler in direct sunlight, while photothermal triggering folds the film to absorb solar heat.

Enhanced Mechanical and Shape Memory Properties of Laser Direct Energy Deposited CoCrFeMn High Entropy Alloy by Carbon Addition

open access: yesAdvanced Engineering Materials, EarlyView.
Feasibility of improving the mechanical and shape‐memory properties of a CoCrFeMn high‐entropy alloy through carbon addition is investigated. The recovery strain of the carbon‐containing alloy is approximately four to five times higher than that of the carbon‐free alloy.

Adapted sampling for 3D X-ray computed tomography [PDF]

open access: yes, 2015
International audience—In this paper, we introduce a method to build an adapted mesh representation of a 3D object for X-Ray tomogra-phy reconstruction. Using this representation, we provide means to reduce the computational cost of reconstruction by way

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
